Record AirSense 11 data over Bluetooth
AirCANnect turns a supported ESP32-S3 board into an AirSense 11 recorder with live charts, local EDF files and browser downloads. A Waveshare board with onboard microSD pairs over Bluetooth and uses USB power; the separate CAN route requires additional wiring. Network-share and SleepHQ exports are optional.
This firmware also exposes therapy settings and firmware flashing. On the Touch LCD 1.54 board, holding PWR starts or stops therapy. Keep those controls separate from data setup and leave prescribed settings unchanged.
